That's what researchers may be on to with new breakthroughs. At Michigan State University, researchers think they have identified synuclein proteins as the cause of aggregation, or clumping, which is the first sign, or step, of Parkinsons.
While scientists don't know exactly how proteins are formed, they do know that as they form, they fold together. This folding can be done incorrectly and clump together, where plaques can form and lead to Parkinsons, Alzheimers, and A.L.S. (Lou Gehrig's Disease).
While not a cure, this is a key first step in not only identifying a cause, but also in one day stopping the disease at inception. They are now looking into ways to stop the aggregation that is the underlying cause. One day, they'll not only be able to stop the initial problem, but prevent it from ever happening in the first place.
